Why is My Check Engine Light On?
Seeing a car’s check engine light illuminated on the dashboard can cast a feeling of dread for drivers who equate the symbol with costly repairs. The warning light indicates a malfunction with one of the vehicle’s systems, but even minor problems can trigger an alert.
Do not ignore your car's check engine light. The warning indicates possibly serious problems but not every alert means steep repair bills.
